Title: Controlling method of light
Inventor: INOUE MOTOICHIRO
IPC: G02F1/01
Filed: 1984-07-31
Abstract: PURPOSE:To remove the loss of diffracted light and to improve control accuracy by detecting the quantity of reduction of light on the non-diffracted light side at the time of diffraction and controlling the distribution ratio of the diffracted light to the non-diffracted light in accordance with the detected quantity. CONSTITUTION:A difference between an output signal obtained at the OFF of diffracted light of an optical sensor PD and an output signal obtained at the ON of the diffracted light is extracted by a coupling capacitor C1 and detected and smoothed by diodes D1, D2 and a capacitor C2. The voltage is applied to one side of voltage determining resistors R3, VR for a constant voltage circuit consisting of TRs Q1-Q5, a Zener diode ZD, a variable resistor VR and resistors R3-R7 and the output voltage of the constant voltage circuit controls a voltage to be applied to a modulating means 2. Consequently, the reduced quantity of light of the non-diffracted light side at the time of diffraction is detected and the distribution ratio of the diffracted light to the non-diffracted light is controlled in accordance with the detected quantity, so that the diffracted light is not lost and the control accuracy can be improved.

IPC: G06T7/00
Filed: 1993-06-30
Abstract: PURPOSE:To recognize the three-dimensional positional attitude of an object with high accuracy by detecting the position and image-pickup angle of a camera detected or not detected for the first time in a range where respective common image pickup point is continued to be detected in an image, and computing the positions of plural common image pickup points from those data. CONSTITUTION:Stacked by scattering round bars 4 are image-picked up from the position where a movable table 3 is located by an image pickup device 2. The center line of the round bar 4 is found from the image of the round bar in prescribed procedure by an image processing device 6. In other words, a bright part on the center line can be extracted by binarizing the brightness distribution of the image of the round bar 4 whose surface is mirror-finished with the illumination of a light source 5, therefore, the center line of the round bar 4 can be found by applying thinning processing to and linearly detecting the bright part. At this time, recognition for the above/below relation of stacked round bars 4 and three--dimensional position detection are not performed. Therefore, the threedimensional positional attitude of the round bar can be found from the images image-picked up from plural image pickup positions by linearly moving the image pickup device 2 on the movable table 3.

Abstract: PURPOSE:To surely carry out ignition and to prevent explosive ignition by providing a high-frequency generation source, an electric wave shielding late with a gas passage hole between a primary and a secondary combustion chamber, and a heater for heating an ignition means and said gas passage hole in the secondary combustion chamber. CONSTITUTION:Garbage in a primary combustion chamber 1 starts to be dried by emission from a high-frequency generation source 6, operation of a blower 9 and an electric current flowing to a heater 18.

Since the igniter 11 is also dried, its electric discharge is generated in a good condition and, when the concentration of gas within the secondary combustion chamber 12 is gradually increased to develop inflammable gas, the ignition is carried out smoothly. Thus, the garbage is thermally decomposed to evolve gas and, after being burnt, it is reduced to carbon and ashes. The carbon is burnt completely by a discharge spark. According to this method, when the gas is concentrated to the inflammable gas, the ignition is surely carried out, and hence explosive ignition can be prevented.

Title: Transmitting and receiving circuit
Inventor: HAGISAWA HIROSHI
IPC: H04M9/08
Filed: 1986-07-11
Abstract: PURPOSE:To perform satisfactory transmitting and receiving and to prevent. side tone by detecting the level of line current, making gain control of a receiving amplifier and a transmitting amplifier to obtain the most suitable level for signal transmission, and at the same time, controlling the level of the receiving amplifier detecting the level of transmitted signals at the time of transmission. CONSTITUTION:When the distance of transmission is large,the level of line current is lowered due to large line resistance. Therefore, the gain of amplifiers 1, 11 is controlled to high gain to make the level of line current high and make smooth transmitting and receiving possible. At this time, the signals that leak from transmitted signals to received signals are amplified largely by the receiving amplifier 1 that became high gain, and accordingly, the side tone becomes large. However, due to the presence of the second gain controlling circuit 13, the side tone is suppressed. the presence of transmitted signals sent out from the transmitting amplifier 11 is detected by a second gain controlling circuit 13 to lower gain of the receiving amplifier 1. Thus, the amplification of the leak signal as side tone is suppressed, and the sound generated from a speaker is made low.
